Application filed February 11, 1909. Serial No. 477,322.

To all whom it may concern:

Be it known that I, Jonas FRANKLIN DIXON, a citizen of the UnitedStates, residmg at Carthage, in the county of Jasper and State ofMissouri, have invented a new and useful Bed-Spring, of which thefollowing is a specification.

This invention relates generally to bed springs and particularly to oneof that type embodying in its construction crossed wires and cone-shapedsprings assembled there-- with.

The ob ects of the lnventlonare in amanner that will at once be simple,practical,

easy to accomplish, and positive in action,

so to connect the crossed wires as to prevent any sliding movementrelatively to each other; to assemble the attaching coils of the wiresin a way that springs with the crossed will secure the coils against thepossibility of becoming detached, and at the same time mutually to bracethe crossed wires and strengthen their union with each other; and

to facilitate assembling of the diiierent elements, thus to reduce thecost of manufac ture and minimize the labor of construction.

With the above and other as will appear as the nature of the inventionis better understood, the same consists in the novel construction andcombination of parts i of a bed spring, as will be hereinafter fullydescribed and claimed.

In the accompanying drawings forming a part of this specification, andin which like characters of reference are employed to indicatecorresponding parts: Figure 1 is a view in perspective on an enlargedscale of a portion of a bed spring embodying the improvements of thepresent invention. Fig. 2 is a view in side elevation, looking in thedirection of the arrow A, F ig. 1. Fig. 3 is a View similar to 2, butlooking inthe direction of the arrow B, Fig. 1.

In describing this invention appropriateterms have been selected andemployed throughout the specification to specify and emphasize thearrangementof the difi'erent parts of the structure, and are to beunderstood as defining the relative disposition of the parts when thebed spring is in use and are as follows attaching coil in referring tothe lower or smallest'whirl of the helical spring, under and over asapplied to the disposition of the attaching coil relatively to thecrossed wires, and upper and lower in designating the crossed objects inview,

wires. I The term lock adopted in connection wlth the assemblage of thecrossed wires is to be considered as meaning a positive intel-locking ofthose parts as by the provision of an eye on one to receive the other,and not merely the employment of kinks or bends such as are commonlyresorted to for bold ing the crossed wires assembled againstdisengagement from each other or from slid- Referring to the drawings, 1designates a helical spring, such as is commonly employed in springbeds, 2 the upper crossed wire and 3 the lower crossed wire. The wire 2is normally straight, but the wire 3 i is provided at each point in itslength where a spring is tobe secured with an eye or loop 4 to receivethe wire 2. As is usual, the terminal of the lower or attaching coil 5is provided with an upstanding toe or finger 6 which by engagement withthe wire 2 will prevent disconnection of the spring from the crossedwires. In constructing a spring bed in accordance with the presentinvention, the following procedures are observed, the description forthe sake of brevity being confined to the assemblage of a single coilspring with two crossed wires.

.The Wire 3 is placed under the attaching coil- 5 with the eye 4 at theapproximate center thereof and projected upward a suflicient distancebeyond the coil to permit the straight Wire 2 to pass looselytherethrough and over the lower coil. By this arrangement when the partsof a complete bed spring are assembled, the plane of the under side ofthe crossed wires 2 will be above and separated from the plane of theupper side mg movement arising from pressure exerted on the structure inuse.

of the crossed wires 3 by a distance a little greater than the diameterof the wire of the this wire downward within the coil and at its center,thereby firmly securing the coil between the two crossed wires, the seat7 formed by the bend in the wire 2 serving to lock the same against anymovement'with relation to the wire 3. In order further to prevent anyslipping of the attaching coil relatively to the crossed wires, by thesame pressure employed in clenching the eye, the wire 3 is kinked upwardand the wire 2 is kinked downward at each of the two points externallyof the coil, forming in the first named: wire seats- 8- and in' the lastnamed wire seats 9 with which the coil engages,

and istherefore held from spreading under 'pressure. The stability ofthe connection between the coil and the wires is still further increasedby the fact that the pressure exerted inclenchingthe eye and informingthe seats 8 and 9 operates to bow or bend the portions of the coil underthe upper crossed wire 2 downward and to bow or bend theportions of thecoil over the crossed wire upward, as clearly shown in Figs. 2 and 3. 1

From the foregoing description it w1ll be seen that by the peculiarmanner of assembling the crossed wires with each other, namely by theprovision of the eye, and the seat-7 these parts willbe positivelylocked together, and further that by the formation under one cross wireand over the other, the

wires being oppositely kinked to provide seats positively engaging thecoil to hold the co1l.and wlres securely assembled, the wlres 'beinstrai ht between the several Joints of shifting, the crossed wires beingstraight between the several points of intersection with each other andthe coil.

3. A bed spring comprising crossed wires one of which is provided withan eye to receive the other, and a helical spring having its attachingcoil disposed under one crossed wire and over the other and encirclingthe eye.

4. A. bed spring comprising upper and lower crossed wires one of whichis provided with an eye to'receive the other, and a helical springhaving its attaching coil disposed under one crossed wire and over theother, thewires being oppositely kinked upon the coil interiorly andexteriorly of the same to lock it against shifting, those portions ofthe coil engaged by thelower crossed wire being bowed upward and thoseportions engaged by the upper crossed wire being bowed downward wherebyinterlocking seats are provided in the coil and the wires.

In testimony that I claim the foregoing as my own, I have hereto aifixedmy signature in the presence of two witnesses.
